Machining Enhancements

Improved Part Setups on 4-Axis Mill Machines

The aPriori Machining process model was updated to ensure that parts made on 4-Axis Mill machines always have two setups and to ensure that GCDs (part features) are assigned to the primary rotational setup when feasible.

The latest Machining process model (CMV350) improves the part setup behavior for 4-Axis Mills. Previously, for some parts, aPriori identified only a single setup. The new behavior reflects the typical practice in which parts are clamped so that some part surfaces are obscured, and therefore need to be setup at least twice to machine all part surfaces. aPriori continues to assign all GCDS that are accessible from the first (primary) rotational setup to that setup. In addition, aPriori now assigns at least one Stock Trim GCD, which represents a margin of material to be removed from one side of the workpiece, to the second part setup.

Note: due to a known issue, the second setup is sometimes incorrectly labeled as the Primary setup instead of the Secondary Rotational setup.
